SARGENT 3540-3550-3570 SERIES POWER SUPPLIES
OPERATION AND INSTALLATION INSTRUCTIONS
MODELS: 3540, 3550, 3570 (24 VOLT); 3541, 3551, 3571 (12 VOLT);
and 737-12 VOLT and 738-24 VOLT BATTERY BACKUP KITS
1. DESCRIPTION
These instructions cover 6 different models:
Table 1 3500 Series Models
Model # Amps Volts Output Circuits
3540 2 Amps 24 Volts CCS-4
3550 4 Amps 24 Volts CCS-8
3570 6 Amps 24 Volts CCS-8
3541 3 Amps 12 Volts CCS-4
3551 4.5 Amps 12 Volts CCS-4
3571 6 Amps 12 Volts CCS-8
The SARGENT 3500 Series power supplies consist of a power module and CCS (Central Control System) control board to
which all connections are made. The board provides terminals for line voltage input and DC outputs on separate circuits so
that a number of devices can be powered. Models 3540, 3541 and 3551 are furnished with the CCS-4 control board with four
separate output circuits. The 3550, 3570 and 3571 are furnished with the CCS-8 control board with eight separate output
circuits. Each output circuit has an on/off slide switch and an LED that displays its status. The CCS control board also provides
an LED indication showing that the power supply is on, emergency release terminals; line voltage, DC fuses and sealed lead
acid-gel cell battery charging are functional. All power supplies in the 3500 Series are Class 2 rated when installed following
these instructions. Always check with your local building department to make sure you are complying with applicable wiring
codes before installing these units.
2. SAFETY
Line voltage input and the battery output present a high voltage shock hazard. If shorted, the battery output can generate
sufficient heat to ignite some materials. Whenever the unit is powered, either by line voltage or batteries, the cover LED is lit.
The supply must only be opened by trained service personnel when the cover LED is on.
Note: Power supplies are shipped without batteries.
3. OPERATING CHARACTERISTICS
3.1 LINE VOLTAGE INPUT
110-120 VAC hot, neutral and earth ground are connected to terminals “H”, “N”, “G” (Fig. 3). This is fed to the input of the
power module through factory made connections.
3.2 DC OUTPUT AND VOLTAGE ADJUSTMENT
3500 Series Power Supplies have adjustable output capable of
charging backup batteries. The power supplies are factory set at
12 volts or 24 volts, respectively. When the battery pack option is
used, the power supply output must be set to 13.5 volts for 12 volt
supplies and 27 volts for 24 volt supplies. If the voltage is to be
changed, use the potentiometer on the power module marked “V
ADJ” (Fig. 1 and 3). The current rating addresses the possibility of
the supplies operating at 12.5% over voltage. Therefore, any supply
which is operated at its nominal voltage (12 V or 24 V) can supply
about 20% more than its current rating. Despite this, SARGENT
recommends that power supplies be operated at no more than two
thirds of their maximum amperage capacity for optimum reliability.
Operating power supplies at their maximum amperage greatly
increases the possibility of heat induced failure.
